Unification and DC Conductivity of PDMS/NiNPs Nanocomposite
Abstract: The DC conductivity of nickel nanoparticles–polydimethylsiloxane (NiNPs–PDMS) composite materials has attracted considerable attention due to their promising applications in flexible electronics, sensors, and energy storage devices. The electrical performance of these composites is largely governed by the formation of conductive networks within the insulating polymer matrix. Incorporating nickel nanoparticles into PDMS introduces conductive pathways that significantly enhance DC conductivity once a critical percolation threshold is reached.Several key factors influence the …

Fabrication and Experimental Investigation on Mechanical Properties of Quartz Particulate Reinforced Aluminium Composite
Abstract: Composites are processed by adding a reinforcement phase in a base metal. The base material is known as a matrix and the constituent that is added is called reinforcement. The matrix acts as a support while the reinforcements attach themselves in their respective positions which results in the synthesis of a material which has different mechanical and thermal properties compared to their raw materials. Since aluminium is used as a …

Development of Web-enabled Smart Hospital Management System: Patient Data Visualization and Real-time Decision Making
Abstract: As everyone is aware, fewer people had access to healthcare services, which prevented many people from receiving the care they needed. The idea that, by WHO criteria, there should be one physician for every 1,000 patients is nearly unbelievable. Yet, India’s current ratio is a staggering 1:1445. This disparity highlights a serious gap in healthcare resources that cannot be ignored. Authors remember speaking with a friend who works in a …
